Expanding Foam

[canada_camper]

Hello, I had to remove the sprayed in foam around the waste tanks pipe. Is there any specific type of expanding foam I should use to fill in the rather large hole?
THX in advance.

Dow GREAT STUFF Gaps and Cracks in the Red can is what I've used for resealing underbelly.
I like it over their Window & Door foam in the Blue can.

Exactly what I was looking at, think I might go with "The Big Gap"

I used this stuff (its black and blends in a little better than the typical yellow foam) - https://www.rona.ca/en/multi-purpose...12-oz-56495018

canada_camper - I found the black foam recommended by sitruc1978 at Home Depot Canada as well. I haven't had to use it yet, but that is my plan when I do.
